2-elements in an Autotopism Group of a Semifield Projective Plane

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2022
We investigate the well-known hypothesis of D.R. Hughes that the full collineation group of non-Desarguesian semifield projective plane of a finite order is solvable (the question 11.76 in Kourovka notebook was written down by N.D. Podufalov). The spread

Linear sets from projection of Desarguesian spreads [PDF]

open access: yesFinite Fields and Their Applications, 2021
Every linear set in a Galois space is the projection of a subgeometry, and most known characterizations of linear sets are given under this point of view. For instance, scattered linear sets of pseudoregulus type are obtained by considering a Desarguesian spread of a subgeometry and projecting from a vertex which is spanned by all but two director ...

SpreadRank: A Novel Approach for Identifying Influential Spreaders in Complex Networks

open access: yesEntropy, 2023
Identifying influential spreaders in complex networks is critical for information spread and malware diffusion suppression. In this paper, we propose a novel influential spreader identification method, called SpreadRank, which considers the path ...

Research on Maximizing Influence of Blockchain Social Network Based on BCLT Model

open access: yesDiscrete Dynamics in Nature and Society, 2022
In the blockchain social network, the traditional influence maximization algorithm has the problem of insufficient accuracy of the influence spread. To solve the above problem, a BCLT model including the characteristics of the blockchain is established ...
